separate the underlying data access logic from the high-level business logic, so that the DAO mode can focus more on writing data access code. The DAO mode is one of the standard J2EE design patterns. developers use this mode to separate the underlying data access operations from the upper-layer business logic. A typical DAO implementation has the following components:1. A Dao factory class;2. A Dao interface;3. A specific class implementing the DaO interface;4. Data Transmission object (someti

During the stress test yesterday, I found a strange problem.

It is found that the JSESSIONID in the cookie changes when get OpenDocument. jsp is used, so it is co

By converting the usual dashboard into flash animation, a dynamic analysis method is provided. This is probably not available in other tools. Below is a simple sample generated by me. On the interface, it can dynamically change the growth rate. The generat

disconnection is destroyed.2. Vo is a value object, the precise point is that it is a business object, is living in the business layer, is used by business logic, it is the purpose of survival is to provide a place for the data to survive.The PO is stateful, and each property represents its current state. It is the object representation of the physical data. Using it, we can decouple our programs from physical data and simplify the transformation between the object data and the physical data.3.

Typically used for data transfer between business tiers, as is the case with PO, which contains only data. But it should be abstracted out of business objects that can correspon
